The rise and fall of the fund is determined by the investment target. For example, equity funds invest in a basket of stocks, and the rise and fall of the fund is determined by this basket of stocks. Invested stocks go up, funds go up, invested stocks go down and funds go down. For example, bond funds mainly invest in bonds, and the rise and fall of funds are determined by the bonds invested, and the bond yield = bond price+bond interest.

Funds can be divided into money funds, bond funds, hybrid funds, stock funds, index funds, ETF funds, LOF funds, QDII funds and so on.
